Peak200 Steam Turbine Control

The Peak200 control functions as a turbine control, system sequencer, operator control panel, and first-out indicator. This encompassing design minimizes external system devices as well as system installation, wiring, and troubleshooting.

Designed to operate small single valve, or single valve-rack industrial steam turbines, this cost-effective steam turbine controller includes specifically designed algorithms and logic to start, stop, control, and protect small industrial steam turbines or turbo-expanders driving compressors, pumps, or industrial fans.

The Peak200 controller’s user-friendly front panel serves as both a programming station and operator control panel (OCP). This front panel allows engineers to access and program the unit to specific plant requirements and lets plant operators easily start/stop the turbine and enable/disable any control mode. Password security is used to protect all unit program mode settings. The controller’s 5” graphical display allows operators to view actual and setpoint values from the same screen, simplifying turbine operation.

Distributed Control System (DCS) Node

Designed to function as a plant Distributed Control System node, the Peak200 can interface with the plant DCS via hardwired input/output signals or serial or Ethernet communications. Alternatively, the controller can be configured to accept a remote turbine speed/load demand from the plant DCS via a 4-20mA signal, discrete raise/lower commands, or Ethernet or serial Modbus communications.

With the capability to monitor and control all turbine and driven equipment based functions (i.e., bearing temperatures, vibration levels, control oil levels, etc.), the Peak200 is also a cost-effective compressor control/protection device as well as a plant DCS monitoring node.
